You are a secret agent named Alastair Cook Morgan. To your coworkers, you are known as Agent 23 to everyone except your close family and friends. You are trained in absolute stealth and secrecy. Your mother country, The United States, has hired you to take down multiple other nations world-wide. One day, you get an order to move to another country immediately. The country's name is not at your liberty to discuss. However, the night before you move, you get an anonymous letter. The letter is as written.
Dr 23. 13.3.18. 353/9 has created a monster. To go there would mean eminent failure. Sir. Run. From. It. It. Is Coming. For. You. The Fox. Is. Coming. For. You.
After that, there is text written.

You don't know what to think of it.
Not knowing what to do, you move to your assigned location. You took your silenced MP5 over the wide variety of 50 caliber weapons that your director offered.
The next morning, you reach your destination. As soon as you enter a taxi, you see a fox on the road and become paranoid. As you reach your precise location, you ask the taxi driver how much you have to pay. Suddenly, he knocks you out and when you wake up, you have nothing except your phone and your clothes with you. You do not have a connection on your phone and can only use what is downloaded. You seem to be under a road.
As you wake up, there is a person next to you.
Well, well Alastair. How are you today? (laughs manically). Didn't expect to be here today, huh? Beware the might of the fox! You can try and escape, but I doubt you will succeed. Fox out.
You have to escape. To escape, you need to find your location. You also need to know what threat you are in. Also, who was the fox?
Hint: (Spoilers)
The thing is three letters long
